Final answer:
Carbohydrates provide energy; proteins are responsible for tissue building and forming growth factors and hormones; fats are integral to cell membrane structure, and vitamins function as antioxidants.
Step-by-step explanation:
Matching each nutrient to its primary function in the body involves understanding the roles that these macronutrients play in various biological processes. Here's how the nutrients match up with their primary functions:
- a) Carbohydrates: B) Provide a quick source of energy for cells and tissues.
- b) Proteins: C) Form tissues, growth factors, and hormones.
- c) Fats (lipids): D) Form structural components of the cell membrane.
- d) Vitamins: A) Act as antioxidants.
It's important to note that carbohydrates, proteins, and fats provide the energy and materials necessary for various body functions. Carbohydrates are the body’s primary source of energy, while proteins are essential for building and repairing body tissues, and fats are important for maintaining cell structure and other functions. Vitamins, while they do not provide energy, play crucial roles in regulating body processes, including acting as antioxidants.
